in order to investigate the effective factors on the reduction of rain-fed wheat yield, an experiment in 45 fields was conducted in the township of bandar-gaz in 2012. in this research, all information such as crop management operations, seedbed preparation, cultivar, site preparation, seed sowing, weed combating, planting and harvesting issues, time of toxicant spraying, used seed rate were co...

Delserone, L. M., and Cole, H., Jr. 1987. Effects of planting date on development of net blotch epidemics in winter barley in Pennsylvania. Plant Disease 71: 438-441. The influence of planting date on fall and spring net blotch epidemics (caused by Pyrenophora teres) was evaluated with the winter barley cultivar Pennrad. Experiments were conducted in Centre County, Pennsylvania, in 1982 and 198...

Edamame soybeans are a speciality food item for fresh and processed markets and they are harvested at a physiologically immature (R6) stage. Bean leaf beetle, Cerotoma trifurcata, is a sporadic pest of soybean in Nebraska, however, its pest status and abundance has increased in the recent years due to an increase in soybean acreage. This was a field experiment aimed at determining the populatio...

Five soybean cultivars, one each from Maturity Groups (MG) III, IV, V, VI, and VII, all susceptible to Heterodera glycines, were planted in H. glycines-infested soil in April, May, June, and July at multiple locations in Arkansas and Missouri. The purpose of the study was to determine whether planting early reduces yield losses due to H. glycines. The population levels of cysts, eggs, and secon...

In order to study the impact of drought stress and planting date on safflower yield and yield components, an experiment was performed in Tabriz region in 2011. The experiment was carried out as split-split plot based on randomized complete block design. The main factor which was applied as split plot includes drought stress  with three levels:  (S1) 80 ± 3 mm evaporation from basin level of cla...

the effects of planting date and single irrigation (si) allocation scenarios on increasing and stability of yield were investigated to determine the total water productivity and economical water productivity (wpe), for rainfed wheat at dryland agricultural research institute in maragheh, iran, during 2000-2004. the treatments included three sowing dates (early, normal and late), four allocation...
